Should your state government suspend gas taxes when fuel prices reach record highs?
California gas prices increased to a statewide average of $6.11 per gallon as of September 18, 2026. This marks a 19-cent jump over the previous week and a $1.40 increase compared to the same time last year.
Why it matters
The rise in pump prices reflects global increases in crude oil costs, which are hovering near $100 per barrel due to Middle East tensions. California households face higher costs than the rest of the nation due to specific state-level taxes and a heavy reliance on imported fuel.
The statewide average of $6.11 per gallon is up 19 cents from the prior week and $1.40 higher than levels recorded in September 2025. Prices in San Francisco have reached $6.23, with some Bay Area stations exceeding $6.30 per gallon.
The players
California
The state government sets tax rates that contribute to local fuel costs and maintains infrastructure that relies on energy imports.
The details
Retail stations adjust prices to pass through costs associated with global crude oil market fluctuations. In California, these market-driven costs are layered on top of state-specific taxes and the logistical expenses of an import-reliant supply chain. The resulting pump price shift directly reduces the discretionary income available to families who rely on personal vehicles for commuting.

Money Landscape
Gas prices in the state are currently experiencing an acute upward pressure that distinguishes the local market from the national average. This movement represents a significant departure from the historical range established over the past year.
Households should review their monthly transportation budget to account for the 19-cent weekly increase in fuel costs. If these expenses require shifts in spending priorities, consider speaking with a financial professional about strategies for managing discretionary expenses.
The takeaway
Rising fuel costs are primarily driven by international crude oil price pressures that amplify existing state-specific tax and import costs. Households may consider reviewing their regular transit patterns and fuel-buying habits to mitigate the impact on their monthly budget.
